Need to know the following based on the information above please show work:

• His relative oxygen consumption when walking.
The formula for oxygen consumption is ( speed m/min ) x ( 0.2 ml/kg/ min per m/ min) + 3.5 ml/ kg/ min
3 mile/ hr X 1 m/0000621 mile X 1 hr/60 min = 80.51 m/ min
O2 consumption = 80.51 m ...

Solution Summary
